◼ Founder’s Message
Get to know our founder - the vision behind Guangzhou CONGSIN inverters
At the center of the CONGSIN inverter factory in Guangzhou, stands a passion for innovation and a dedication to quality, shaping one of the most trusted inverter brands in South China.
Mr. Xiao, who is 45 years old now, began his journey after graduating from university. With a background in power engineering and a strong entrepreneurial spirit in programming and design, he and his father established a small inverter shop at that time, focusing on developing reliable power inverters for local customers.
In the past twenty years, Mr. Xiao has transformed this humble beginning into a thriving inverter manufacturing enterprise, which has gained widespread recognition in Guangzhou and other regions. His leadership philosophy is simple yet powerful:
"Build every inverter as if it were powering your own home."
Under his leadership, CONGSIN has developed into a well-known enterprise known for its technological precision, product stability, and customer trust. From off grid pure sine wave inverters to advanced UPS models, as well as the latest remote control inverters, the factory's innovation has helped countless global partners expand their energy solutions.
Nowadays, almost every inverter expert in Guangzhou knows the CONGSIN brand, which proves Mr. Xiao's persistence, foresight, and lifelong dedication to the power conversion industry. His story continues to inspire the next generation of engineers, who also believe that quality is not a behavior, but a habit.
